Abstract: In an atmospheric-pressure plasma processing apparatus, a first metal surface 21a of a first stage portion 21 of a stage 20 is exposed and an object to be processed W composed of a dielectric material is placed on the first metal surface 21a. A second stage portion 22 is disposed on a peripheral edge of the first stage portion 21. A solid dielectric layer 25 is disposed on a second metal 24 of the second stage portion 22. A peripheral portion of the object W is placed on an inner dielectric portion 26 of the solid dielectric layer 25. An electrode 11 generates a run up discharge D2 in a second movement range R2 above the second stage portion 22. Then, the electrode 11 is moved to a first movement range R1 above the first stage portion 21 and generates a regular plasma discharge D1.

Abstract: The object of the present invention is to reproduce conditions where viral proteins can function along with the original life cycle of the viruses and to establish an expression system which can evaluate the function of viral proteins by a reporter gene without generating infectious viruses. The present invention provides an assay system comprising a vector containing DNA coding for RNA virus-derived RNA-dependent RNA polymerase and a vector containing a reporter gene expressed in the anti-sense direction.

Abstract: An aqueous grinding fluid has compositions mainly consisting of 40.0-95.0 wt. % a polyalcohol and/or a polyalcohol derivative, 5.0-50.0 wt. % water, 0.1-3.5 wt. % bentonite, 0.1-5.0 wt. % cellulose and weight %, 0.5-10.0 wt. % mica and optionally a small amount of a surfactant or polar solvent. Bentonite, cellulose and mica are preferably added with such combination to adjust a viscosity of a slurry to 150-300 mPa.second as a value measured by a rotating cylinder type viscometer. The aqueous suspension is nonflammable and stabilized in dispersiveness and settleability-proof of abrasive grits as well as a viscosity for a long time, and facilitates washing and cleaning of sliced wafers and a grinding machine without radiation of stinks.

This vector is useful to elucidate the mechanisms of RNA virus replication and of the development of RNA virus infections, and to develop therapeutic agents and means of treatment, and so on.

Abstract: Slurry useful for wire-saw slicing has viscosity adjusted to 400-700 mPa·second at a shear speed of 2/second and of 50-300 mPa·second at a shear speed of 380/second. The viscosity of slurry is measured using a cone and plate type viscometer which can measure viscosity at different shear speeds. Since the slurry sufficiently flows into inner parts of grooves formed in an ingot and consumed for wire-saw slicing due to the viscosity controlled in response to the shear speed, the ingot can be efficiently sliced to wafers or discs.

Abstract: A newly proposed wire cleaning apparatus used for removing slurry from a wire, which reciprocatively travels between a slicing chamber and a wiring chamber. The wire cleaning apparatus has a couple of multigrooved guide rollers 41, 42 rotatably provided at a cover 30. A slurry receiver 20 is detachably attached to the cover 30. A centrifugal force is generated during repeated reciprocative movement of the wire 5 between the multigrooved guide rollers 41 and 42. Slurry is shaken off from the wire 5 by the centrifugal force and gathered in the slurry receiver 20. Removal of the slurry is accelerated by spraying a cleaning liquid W at the same time. Introduction of the cleaning liquid W into the slicing chamber is inhibited by on-off control of the cleaning nozzles 41, 42 in response to a travelling direction of the wire 5.

Abstract: An ingot 9 is sliced to wafers by a wire 5 which travels around grooved rollers 1 to 3. A tension applied to the wire 5 is detected by tension sensors 21, while vertical displacement of dancer rollers 19 is detected by position sensors 20. At least one of a fluctuation gap of the tension, a fluctuating velocity of the tension, an acceleration of the fluctuation, vertical movement of the dancer rollers 19, a velocity of the vertical movement and acceleration of the vertical movement is calculated from the detection results, and compared with a threshold in a calculating circuit 23 to judge a sign predicting abnormal increase of the tension. When the predicting signal appears, a command signal is outputted from the calculating circuit 22 to a controller 23 to stop operation of a wire-sawing machine or to relax the wire 5. Since rupture of the wire 5 is prevented in bud, a wire-sawing machine is efficiently driven for slicing the ingot 9 with a high productivity.

Abstract: If something goes wrong with a wire saw, a personal computer outputs a dial signal to a modem, which dials a calling number of a pager carried by an operator through a telephone system. The sound of the pager notifies the operator of the abnormality of the wire saw even if he or she is not in the vicinity of the wire saw.

Abstract: A sensor measures a displacement of a sensor, and a control part of a wire saw calculates a sliding load in accordance with the measured displacement and an initial tension of the wire. Then, the control part compares the calculated cutting load with a preset reference value, and controls an ingot feed speed for a drive unit of a workpiece feed table in accordance with the results of the comparison.
